Application of optical powder in injection molding and printing

The use of optical powder is determined according to its actual situation. Different requirements, different brightness and different uses have different methods of use. According to the product, the solution suitable for its own in the actual production process can be summarized.

Xingsheng light powder is used for injection molding: the ratio of light-varying powder to plastic material is generally about 4%-10%, depending on the color depth of the product, the light color is less, and the deep color is added.

First, the ingredients: first add the diffusion oil into the raw material for a minute, then add Xingsheng light powder to stir for one minute, then add the color powder for two minutes, the mixing time should not be too long, pay attention! Light powder is most likely to be rubbed with iron. Too long will blacken the raw materials.

Second, the injection molding machine: the injection molding machine should be cleaned, the temperature should be adjusted to the minimum, can be injected, the time in the injection molding machine should not be too long, so as not to burn, the products injected by different machines, there are also differences, new machines and old Machines, domestic machines and imported machines, all need to be solved slowly.

Third, light change powder: light change powder in the injection molding for various reasons, injection molding technology, injection molding machine, the temperature of the dissolved material may cause blackening, short-acting luminous powder (zinc sulfide luminous powder) in the injection molding blackening performance a little.

Xingsheng light powder is used for printing: In order to reduce the problem of light-varying powder in coatings, it is possible to use high-viscosity resin and add anti-settling agent. Stir well before use. Adjust the viscosity with thinner. Do not use heavy metal compounds as additives. The printed background is dominated by white or reflective colors to increase the brightness and illumination time of the printed pattern. The coating and ink coating thickness is preferably greater than 100μ, such as 130μ~150μ, which is the best effect (using 80 mesh screen printing, this thickness can be achieved in two passes).
